The Sightmark Core Shot A-Spec LQD reflex sight is a compact red dot optic built for shooters who need a fast, lightweight aiming solution on tactical rifles, shotguns, and carbines. At just 28mm wide and 18mm tall, this 1x magnification sight mounts directly to any Picatinny rail and stays out of the way without adding bulk or weight. The matte black finish avoids glare and blends seamlessly with modern firearms.
What sets the Core Shot apart is its fixed 5 MOA red dot reticle—large enough to pick up quickly at close range, fine enough for precise shots at distance. Whether you're running a home defense shotgun, a 3-gun competition carbine, or a patrol rifle, this reflex sight delivers the speed and situational awareness you need. No magnification means both eyes stay in the fight, and no batteries required to function means you get reliable performance when it matters.
The A-Spec LQD design hints at a sight optimized for real-world duty use. Its compact footprint and Picatinny compatibility make it a straightforward drop-in upgrade for any modern rifle, shotgun, or carbine platform. The matte finish resists reflection in bright sunlight and won't broadcast your position in low-light scenarios.

The Core Shot A-Spec LQD mounts to any Picatinny rail, making it compatible with AR-platform rifles, shotguns, carbines, and most modern tactical firearms. Check your platform's rail system to confirm Picatinny compatibility.
No. This is a passive reflex sight with no battery requirement. It operates by reflecting light off the internal mirror and lens, giving you a reliable aiming point in any lighting condition without electronic power.
The 5 MOA dot covers a 5-inch circle at 100 yards. This size is ideal for fast target acquisition at intermediate ranges while remaining precise enough for accurate shots at distance. MOA (minute of angle) is the standard measurement for reticle size in shooting sports.
Yes. The compact Picatinny mount works on any shotgun with a rail-mounted receiver or top rib. It's particularly popular on tactical and home defense shotguns where fast target acquisition matters.
